The first such theater, the Cooper Theater, in Denver, featured a 146-degree louvered screen (measuring a massive 105 feet by 35 feet), 814 seats, courtesy lounges on the sides of the theatre for relaxation during intermission (including smoking facilities), and a ceiling which routed air and heating through small vent slots in order to inhibit noise from the building's ventilation equipment. [1]. The other two theatres were built in a similar format, however, the last theatre, the Indian Hills Theater had a slightly larger screen and other improvements.

Each element of the theaters was designed to enhance the Cinerama experience. The circular design took advantage of the discovery that patrons, if left to their own devices, would seat themselves in an oval pattern. The exterior circular shape served as a constant reminder to passing motorists that this was a Cinerama theater. The design included a cylindrical shape and a flat roof.

The base of the building exteriors consisted of black Roman brick. The upper portion of the exteriors were clad in insulated Monopanels which were a burnt-orange color called "Swedish red."

His pioneering work in residential solar technology led to lectures at the Smithsonian Institution, solar conferences and universities across the U.S. Crowther's architecture publications are still used to teach students. His "Sun-Earth" text has a reputation for setting a benchmark in holistic architecture design, with arguments outlining economic and environmental benefits. He practiced what he preached, both by living and working in holistically designed spaces, and by a diet replete with organic and natural foods.

In 2006, Crowther was interviewed by filmmaker Jim Fields, for his documentary movie Preserve Me A Seat, about the grass-root failures and successes of activists working to preserve historic movie theaters in Boston, Chicago, Omaha and Salt Lake City.[1]

The Cooper theaters and many of Crowther's other designs have been demolished. He particularly regretted seeing one of his energy-efficient homes expanded into a larger but inefficient showcase.
